I have a new 460 going in my 1976 Rogers. Since the existing engine is out now might be a good time to rebuild the Berkely 12 JC-A pump? It's been previously rebuilt but I don't know exactly when. The packing is not leaking. the front bearing has no play, no perceived unusual vibration. The boat ran with ease to 80mph no performance problems. I have been told that you would hear a "Growling" noise if the front bearing is bad. With the headers, there is no way one could hear anything other than the motor/exhaust. I watched a U-Tube video that indicates the pump can be removed out the back with the engine installed, although the local boat repair shop says the motor needs to be out. I'm past buried in the full roller, forged everything, new down to the ignition wouldn't mind waiting until next winter for the pump but; Since it's out now anyway just wondering; Any suggestions would be appreciated.

Those 'while its apart...' things add up quickly and kill your budget.

You can pull the jet with the engine in the boat.  A 3-point mount needs to be supported in the rear with a cherry picker or hoist.

Since you know the history of the jet, I would be tempted to just run it.

I would suggest pulling the bearing cap off the front of the suction to inspect the thrust bearing.  Check it for corrosion and pitting.  Hopefully you have been keeping the bowl bushings oiled.

The impeller needs to come off to measure the wear ring clearance and inspect the bowl and impeller vanes.

Good luck,

Joe

Gorgeous boat! I think I remember this boat if I'm not mistaken cause I was in love with it lol. Doesn't your boat have an all polished pump with a drop and a ride plate on it?

Holy Smokes!!! that boat is UNBELIEVABLE!!!

First, I would check the leading edge of the impeller for damage.

Easy to check the front to rear tolerance at the wear ring. If its good, and no damage, run it.

If there is any damage, I would definitely pull the bowl, and check the trailing edge. A good time to look at the vanes in the bowl.

If the trailing edge is good, run it. If there is damage, time to pull the impeller for repair or replacement.

At that point, checking the impeller skirt and wear ring for tolerances.

A sloppy wear ring is an easy 500 rpm gain on a modest hp engine, and probably more on your set-up.

So easy, a caveman can do it.

That’s real bummer. I have a berk suction housing that’s complete and in decent condition if you are interested in trying to get the boat going.

UPDATE; Meet Toni at the shop today and watched as he finished my pump. It was definitely in need of a rebuild. Family issues were the delay, all is well again except. On the way home yesterday I stopped and put down a deposit on a new Nitro Bass Boat. The wife never liked the Rogers only rode with me once last summer anyway. I will take my time installing the pump and the additional fuel, wiring, etc. I may list it for sale don't know yet.
Anyway, Thanks to the folks who were willing to lend assistance.

Sweet! Great news!
